Absence of melanin effects. Skin carotenoid scores by RS (a) and RRS (b) versus skin melanin indices measured, respectively, for 160 subjects with widely varying skin melanin levels. Skin melanin indices were measured with a Konica Minolta reflection instrument. The low correlation coefficients and high p-values in both plots prove that RS and RRS skin carotenoid scores for the used devices are not affected by melanin absorptions.
